heres a very old and working iron its gravity fed and boy does it get hot ;im not sure of the year but it sure is in good condition for the age ;maybe in the 30s i have found 3 so far searching and one went for over 200 bucks at an auction ;do enjoy
I have similar device, but it's claimed to be for spirit (nobody knows for sure, original user/owner passed away a long time ago). The valve is leaking, so in the dark it looks like ship in flames (it has numerous round holes in the sides, those look like windows)
nice to know another member has one of these and yes they are gravity fed and boy do they get hot at times i had to use a wet cloth as the tank and handle got quite hot ;i had the same problem with mine leaking around the control valve i re packed it and now it works like new ;rare thats for sure i did a search one day to see how many i can find and only 3 ;one sold for a little over 200 bucks ;mine i found at the local flea market for 40; thou i cant get the mrs to press a pair of pants with it hehehe ;
seems the mrs growing up back in the day used a few of these things and her arms are worn out ;so if i need anything pressed i have to do it and what fun it is
